| Abstract/Contents: | "The fairway consisted primarily of annual bluegrass (70%) and Kentucky bluegrass (30%). Applications were made when flowering dogwood was in full bloom. Treatment plots were 8 x 6 ft, arranged in a RCB design and replicated 4 times. Liquid formulations were applied with a CO₂ compressed air sprayer with four 8004VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and applied in 908 ml of water/48 ft² or delivering 5 gal water/1,000 ft². At treatment time (16 May), the following soil and environmental conditions existed: application time, late morning; air temperature, 70°F; soil temperature at 1 inch depth, 74°F; soil temperature at 2 inch depth, 68°F; RH, 48%; amount of thatch, 0.25-0.50 inches; soil textural class, clay loam; soil particle size analysis: 21.2% sand, 45.1% silt, 33.7% clay; soil moisture (oven dry weight), 50.1%; organic matter, 7.0%; water pH, 7.0; soil pH, 5.8; application time, mid-morning; and skies were clear. Immediately after treatment, each replicate was irrigated with 0.0588 inch of water/48 square feet. Posttreatment counts were made 37 d later (22 Jun). Annual bluegrass weevil control was evaluated by removing four 4 inch cupcutter sod samples from each replicate, and recording the total number of annual bluegrass weevil life stages (larva, pupa, adult) per cupcutter sample. Totals were then converted to a ft² count. Annual bluegrass weevil adults were actively observed on golf course fairways, greens, and roughs before treatment. No treatments provided significant control including Dursban Pro. No phytotoxicity was noted." |
